' rl`his invention relates to internal combustion engines and refers more particularly to `the sleeve valve type yof engine. Infthis type of yengine the upper Vextremity of the Vsleeve `5 or sleeves ordinarily works in a pocket formed between the cylinder" head and cyl inder. While the cylinder head is `ordinarily jacketed for lcooling water,Y the amount of available jacketing is limited due tospark 10 plug location and general arrangement of parts. As `a result the sleeve jacket tends to become overheated resulting in carbon accumulation and general inefficient operation of the engine.`

One of the objects of my invention resides `in providing means for overcoming the above objectionable characteristics. To this end I have provided improved means associated with the cylinder head and `cylinder `20 head cover for causing a -positive circulation of cooling water for cooling the cylinder liead,fsleeve pocket, and spark plug.

I have provided a member preferably in `the nature of a simple sheet metal stamping l `25 associated with thecylinder head and cover for guiding the water in the desired circulating path. One feature of my invention resides ina construction which will not require division of the cylinderhead jacket by i 3o partitions, thus simplifying the casting operations and reducing the manufacturing lcost.

Further features and advantages of my invention reside in the simplicity of the parts,

435 lightness of weight, and ability `tc be manufactured `at low cost.

Further features of my invention reside lin the novel combination and arrangement of parts more particularly hereinafter described and claimed. Y

In 'the drawings reference character 10 represents one or more engine cylinders with associated sleeve valve 12, the latter foriillustratien being shown as the Burt-Mc- Collum single sleeve valve type in which the sleeve is moved in a combined reciprocating and oscillating path with respect to the sleeve axis in moving the sleeve ports 13 to function with the cylinder ports 1st.

The cylinder is closed at the top by a cylinder head 15 Which maybe formed with walls 16 and 17. The wall 16 .together `with the `associated cylinder forms a valve pocket 17 a accommodating the movement of the upper portion of the sleeve valve 12. The wall 17 is spaced from the wall 16 to formthe cylinder head cooling water jacket 18 and also defines the combustion chamber 19. The wall 17 may be extended to provide a barrel 20 with the spark plug opening 21` for spark plug 11. The cylinder head `15 may be secured to thecylinder by studs 22 `at the corners vof the cylinder head flange 23.

The cooling water from acket 2a is open for communication with the cylinder head jacket 18 through opening 25 preferably mainly along one side only of thecylinder head as shown in Figs. 1 and 5. For guiding the water from opening V25 I have provided a member 26 preferably formed of a sheet metal stamping. The member 26 may be formed with wall 27 spaced from the side'of the cylinder head adjacent the opening 255 side walls 28, and top wall 29. The water in moving across the cylinder head is caused to circulate downwardly into the jacket 18 by reason ofthe. baliies 81 preferably formed integrally with the main body rlhe top wall 29 is formed with a semi-circular or recessed portion 32 engageable with the barrel 2O prefer'- ably below the sealing structure or ring 33. A .nut 34 threadedly engages barrel v2() for clamping the cylinder head cover 35 and iso usu

ico

sealing ring 33 in position as shown in the drawings.

The members 2G may be conveniently seated on the'tops of the cylinders l() intermediate the cylinder heads 15 and cover 35. The baiiles 3l preferably are located between the plane of the cylinder axesand the side oic the engine having the water openings 25. By such an arrangement the water is de- Hected downwardly into the cylinder .head jacket 18 insuring adequate and improved cooling particularly for the spark plug ll at the opening 21. In some instances I may provide the barrel ring liange 30 with the .strengthening webs 38 above and outside of the cylinder head jacket 1S, these webs to a slight degree preventing passage of water across and above the cylinder head jacket. rlhe baliles 3l deiiect practically all of the water into the jacket and if desired the webs 38 may be dispensed with.

The cooling water may he circulated throughout the entire system by the usual water pump (not shown), the water being returned to the usual radiator by a header 37 on the outlet side of bailies 3l.

My invention is obviously equally well adapted for use with various types of sleeve valve engines such as multiple or single sleeves having various movements.
